Response Timer
This field indicates the minimum amount of time in seconds the HSC line will wait for an
acknowledgment before polling the remote station after transmitting a LLC frame. This field
toggles the following time selections:
1.00, 1.68, 2.00, 3.00, 4.00, 5.00, 6.96, 10.44, 13.92, 17.40
Select a time greater than the expected delay of the network in order to avoid unnecessary
polls. The default for Frame Relay lines is 3.00 seconds.
Inactivity Timer
The Inactivity Timer field is used to determine how often a poll frame is sent for inactive
links.
Valid entries range from 10 to 255 seconds. The default is 30 seconds.
Retry Count - N2 on Frame Relay LLC Options panel
This number specifies the number of times the software will retransmit a frame, after not
receiving an acknowledgment. LINCS will wait the amount of time specified in the Response
Timer field before retrying the transmit. The value range is 1 to 99, and the default is 10.
